Title: Falling through world on login (NOT CRASHING

Version: 1_0_3

OS: Windows 8.0

Java Version: Java 7 Update 25 V7.0.250 / Java 7 Update 17 (64-Bit) v7.0.170

Description of Problem:

When logging into a friends SMP world, or changing dimensions, there is a 10-20 second lag where I fall through the world. Chunks load fine, but the ground isn't solid. After falling for awhile, I appear back where I started, without dying.

(drop down for version only gives me 1_0_3, but I am using recommended version 1.1.10)

To add on, he is hosting his world by opening to lan, and through Hamachi.

Update your Java version first, since that often has to do with how data is read on transfer.  Unfortunately, this just sounds like a bad case of server-client comms lag, and Hamachi may have a lot to do with it.
